keygen object

Browser support:

Allows a form to be submitted with key encryption. The element generates a secure key and submits the public key with the form.

A selection list belongs to the keygen tag. The user can choose the type of the RSA key pair generation ('medium grade', 'high grade') with this selection list.

This tag is deprecated, do not use it.
